enzymatic |
|
exudation |
|
Secreting a digestive exoenzyme; in carnivorous plants. |
|
oil-secreting |
|
exudation |
|
Producing and exuding an oily substance, often aromatic; when oil-secreting glands are indicated in the nominative, often they are called simply oil glands. |
|
glandular 2 |
|
exudation |
|
Anatomically distinct and producing and exuding a particular substance. |
|
laticiferous |
|
exudation |
|
Producing and exuding latex. |
|
salt-excreting |
|
exudation |
|
Accumulating salt and discharging it directly to the exterior in a concentrated aqueous solution, the salt then crystallizing on the exterior following evaporation of the fluid medium; when salt-excreting glands are indicated in the nominative, usually they are called simply salt glands. |
|
nectariferous |
|
exudation |
|
Producing and secreting nectar; when glands are nectariferous, they are usually indicated nominatively as nectaries. |
|
face |
|
FEATURE |
|
A relatively large, flat or shallowly curved portion of the external surface of a three-dimensional structure, bounded by more or less distinct topological discontinuities. |
|
surface |
|
FEATURE |
|
The exterior or bounding area or layer of any structure, regarded as being infinitely thin; usually described as to relief, reflectance, and/or vesture. |
|
micropyle |
|
FEATURE |
|
The small pore in the integuments of an ovule at its apex, through which the pollen tube grows; or the corresponding aperture or scar in the coat of the seed that develops subsequently. |
|
bud-scale scar |
|
FEATURE |
|
A scar on a stem due to abscission of a bud scale. The scar(s) encircle(s) the axis to which the bud was terminal, each single scar having an outline like that of a transverse section through the base of the bud scale that was inserted there. Sets of bud scale scars (one set per bud) usually delimit seasonal stem growth increments in temperate zone taxa. |
|
groove |
= colpus, fossula, furrow, sulcus, vallecula |
FEATURE |
|
A longitudinal depression that is relatively shallow and narrow. |
|
punctum pl. puncta |
= dot |
FEATURE |
|
A small, generally round sector of distinct coloration or relief. |
|
papilla pl. papillae |
|
FEATURE |
|
A small, conoidal protrusion resembling a pimple. See also pustule (blister, bulla). |
|
stipule scar |
|
FEATURE |
|
A scar on a stem or petiole due to abscission of a stipule; having an outline like that of a transverse section through the base of the stipule inserted there; variously disposed, usually in pairs, adjacent to a point of leaf insertion, sometimes confluent with the leaf scar, sometimes confluent with stipule scars associated with an opposite leaf, the two sets of scars then more or less encircling the axis. |
|
ridge |
|
FEATURE |
|
A very narrow, elongate, relatively low protrusion; esp. on fruits in Apiaceae (Umbelliferae). |
|
spot |
= blotch, macula |
FEATURE |
|
An area that differs in color from the rest of a structure's surface, usually due to differing coloration. See also eyespot. |
|
suture |
|
FEATURE |
|
An evident line of ontogenetic union. |
|
dot |
= punctum |
FEATURE |
|
A small, generally round sector of distinct coloration or relief. |
|
pustule |
= blister, bulla |
FEATURE |
|
A relatively coarse, rounded protrusion or convexity. See also papilla. |
|
furrow |
= colpus, fossula, groove, sulcus, vallecula |
FEATURE |
|
An elongate depression that is relatively shallow and narrow. |
|
lumen pl. lumina |
|
FEATURE |
|
A space enclosed by the wall(s) or membrane(s) of a structure. |
|
tubercle |
|
FEATURE |
|
A small, rounded, knot-like swelling or wart-like protrusion. |
|
fossula pl. fossulae |
= colpus, furrow, groove, sulcus, vallecula |
FEATURE |
|
An elongate depression that is relatively shallow and narrow. |
|
stoma 2 (strict sense) pl. stomata |
= stomatal pore |
FEATURE |
|
The aperture between and regulated by the two guard cells of a stomate (stomatal apparatus). |
|
pit |
= fovea, scrobis |
FEATURE |
|
A small, rounded depression. |
